We are testing the DPAA driver on several DS and RDB platforms and itis working properly. The issues you encounter with it on the X5000/20are likely caused by some issues specific to that particular platform.The device tree that you mention, cyrus_p5020.eth.dts is not found inthe Linux kernel sources. The cyrus_p5020.dts file from the fsl ppcdevice tree folder does not include the PHY information for the DPAAinterfaces. The problems that you experience may be caused by someissues with the PHY configuration (i.e. internal delay). I suggestthat you connect the DPAA interface to a traffic analyzer or directlyto another device on which you can capture the incoming traffic andcheck that the received frames are correct.
